Le Coucher de la Mariée or Bedtime for the Bride or The Bridegroom's Dilemma is a French erotic short film considered to be one of the first pornographic films (or "stag party films") made. The film was first screened in Paris in November 1896, within a year of the first public screening of a projected motion picture. The film was produced by Eugène Pirou and directed by Albert Kirchner under the pseudonym Léar.
